Abstract: The present investigation entitled, to comparative study of microbiological properties of silage prepared form maize, multicut sorghum and hy. Napier (Phule Gunwant) was carried out at division of Animal husbandry and dairy science, college of agriculture, Dhule. During study silage made from three different crops treatment viz. T1-Maize (African tall), T2-multicut sorghum (COFS 29) and T3- hy. Napier (Phule Gunwant), respectively. This all treatment fodder were grown on fodder production unit at division of AHDS itself and used for silage production. Maize was harvested at 50% flowering i.e. milking stage or dough stage and multicut sorghum and hy. Napier grass are harvested/cut after 45 to 60 days each and all the treatment fodder crops were ensiled with bag method. Fodder crops are chopped at size of 4-5 cm piece with the help of chaff cutter. Chopped fodder was filled into each bags layer by layer compacted every layer by continuous treading to remove air and the silo bags were sealed immediately with an air-tight rubber/ rope once it was filled and stored the same at cool and dry place for 60 days. After 60 days of fermentation period, all the bags filled with the different treatment fodder were opened and samples were analyzed to assess the microbiological quality of the same. As microbial parameter point of view we seen the population of bacteria, fungi, actinomycetes and population of yeast in the silage of each treatment. Results about microbial properties all the parameters like population bacteria, fungi, actinomycetes and yeasts found significant, for population of bacteria treatment T₂ (8.40 CFU ml^-1) found significant followed by T₁ & T₃, population of fungi treatment T₃ (15.01CFU ml^-1) found superior over T₃ & T₁ and population of actinomycetes treatment T₃ (18.17 CFU ml^-1) found significant followed by T₁ & T₂ and for population of yeasts treatment T₁ (6.03 CFU ml^-1) found superior over T₃ & T₂ respectively.
